A reduction in swept capacity of over a third will be something of a fundamental shift in mindset for AMG, which has always gone for the 'bigger is better ... then go a bit bigger just to be sure' mentality when it comes to engines. OK, so we've already had a twin-turbo V8. But that was 5.5-litre so hardly downsized.
turbo V8 from Audi is already on the market in RS models (and Bentleys) and, though it must really annoy AMG, there's little choice but to keep within this limit.
Little doubt it'll do the numbers performance wise. But will it sound good?
The sound engineering that's gone into the C63 is, I think, absolutely perfect. There's a showy little blip of revs when you fire it up - I've taken to leaving the driver's door open of a morning when I first start up to bask in its glory - which is possibly a bit contrived. But other than that it seems remarkably free of the over stimulated theatrics performance car exhausts from hot hatches to supercars now feel it necessary to include. The C63 soundtrack is pitch perfect though. Loud enough to be noticeable without ever actually being unsociable enough to have people tutting, the way they might have if you were in a Subaru with a bean tin back box. Fire it up in a Waitrose car park and heads will turn, looking for the source of the noise. But it'll be a reflex action, not a 'who let that chav in here?' disgust. And they definitely wouldn't expect it to have come from the grey Mercedes estate either.
Boy, when you're pressing on though... The savage crack you get on full bore upshifts about one time in every five just makes me giggle. Some newer cars, A45 included, have been programmed to do it every time you change gear meaning the novelty is lost. The '63 will only do it every now and then, which makes it all the more exciting when it does happen. You'll probably now be thinking 'right then, where's the video...' A new clip is on the to-do list. Meanwhile here's the launch control one from a while back to hammer home the point.
Other observations on life with the 507? Well, in Comfort mode (my default for daily driving) the time consuming process of navigating the gear selector from P to D and 'soft' step-off actually makes for an embarrassingly slow departure off the line. I've not been parped from behind yet but no doubt a few have been mystified as to why I'm so slow away from the lights. There's always S or S+ mode but that's a bit savage for town driving. There's always the occasional Race Start option to liven things up of course. Or perhaps holding it on the brake and doing a proper rolling burnout up Teddington High Street.
Yes. That's what we need for next month. More noise. And some tyre smoke. On the case.
